One of the false morel mushrooms, Gyromitra esculenta, was administered p.o. to Swiss mice that were 6 weeks old at the beginning of the experiment. The mushrooms were fed to the mice for 3 days and were followed by a semisynthetic diet for 4 days each week for life. The treatment induced tumors in the lungs, nasal cavity, blood vessels, forestomach, glandular stomach, cecum, and liver in the f...

Trifluralin, a widely used herbicide, added to the diet before the p.o. administration of benzo(a)pyrene (BP) and fed continuously, significantly inhibited the induction of lung and forestomach tumors in female A/J mice. Dietary intake of trifluralin before the administration of BP resulted in a significant increase in glutathione in lung and forestomach but not in liver and glandular stomach. ...

objective: considering the importance of integrin molecules in the implantation and lack of sufficient information in the expression pattern of these molecules in various phases of estrous cycle. it seemed to be necessary to investigate these molecules in mouse endometrial during the various phases of oestrous cycle. materials and methods: female nmri mice (n=15) aged 6-8 weeks were studied. v...

for the 2% diet). to protein in vivo (20, 21). lt is possible, therefore, that SO and BHA were carcinogenic in the forestomach via a similar "nongenotoxic" mechanism of action, i.e., the stimulation 01' cell division induced by cytotoxicity and regenerative hyperplasia. This mechanism has been postulated for various forestomach carcinogens (22). BHA was demonstrated to have a strong hyperplasio...
